Adds two or more control or audio lines together. Besides performing a mathematical add operation on two (or more) control lines, the most common use for this Node is merging two (or more) audio lines.
This node has a configurable number of Audio/Control inputs. See the Number of inputs setting.When inputs of different channel counts are connected, the output channel count will be the same as the greatest input channel count, and all other inputs will be automatically up-mixed to that channel count.
Audio and Control lines (visualized with blue and purple, respectively) are both analogous to an analog signal. They can be used interchangeably, and, for example, an Audio output (blue) can be connected to a Control input (purple), or vice-versa.
